I have a very specific question about brakes and the GAP tail. I've been investigating a ride on the Great Allegheny Passage, which is a rail-trail and I see that there is a "Max 2%" grade on the trail with the greatest change occurring from around Frostburg MD, to Cumberland, MD (~2000 ft/17 miles).
Since we have little experience with big hills and grades, can anyone comment on this section of the GAP trail with a tandem? We've never been on a rail-trail where we didn't have to pedal, and I'm guessing that the GAP is no different, but what do I know, our NJ rail-trails are pretty flat. Since we don't have a drum brake I'd be concerned if I had to drag my rim brakes for 17 miles.
